l'oal whom i5 may colwen.: t

Be it known that I, A. T. LACKLAND, ot

r'St. Uharies, in the county of St. lQharles, inf' the State of Missouri, have invented-a new and useful Improvement in Steam-Boilers; and Ido hereby declare that the following is a full and exact description Ithereof.

` Q. The nature of my inventionconsists in the arrangement of the furnace forthe tire 'inside ofthe boiler in such a manner that the 'llames' pass 'through `the `boiler and return back 4through a Hue orlueS tothe chimney in front, instead of passing under the boiler, as in the old plan. ,The forni of my`boiler is such that it saves nearly,allofthe'heat ofthe fire, very little being` lost by. radiation, the boilervtself forming every part ofthe furnace, except the grates atv the bottoni and the doors in front;l

and the water in the'boiler of course being ull around ,the fire, except at the grates aud'tredoors, a greater Surface is exposed 'to there,

so that; the water Vcan be heated with less fuel than in any other Way. e

p To enable others Skilled in the art to make* and use my boiler, I will proceedto describe its construction.

I apply to it' gagecoolis, sattymfalves, and` other usual appendages of ordinary boilers. i ,There goes in the front of the boileratdand Y passes through the-bone; .to therninupemi,

and returns through't'he flue or l'ues bito' the' chimney in front. r The `lueor iues bis surrounded by Water a and a." je is water under the furnace,except Wherejthe grates are. The- Water a, c, and c all connectsimthe boiler, as you see frornthe center ,cut or cross-'sec- Y tion of vthe boileriu Figure 4. vThe waterl a,
